1. Introduction

Memento ("we", "our", or "us") is committed to protecting your privacy. This Privacy Policy explains how we collect, use, disclosure, and safeguard your information when you visit our website or use our application.

2. Local-First Architecture

Our core philosophy is "Local-First". This means that your personal notes, uploaded documents, and generated knowledge graphs are processed and stored locally on your device whenever possible. We do not have access to the content of your private knowledge base unless you explicitly choose to sync it with our cloud services for cross-device access.

3. Data Collection

We may collect certain information about you in a variety of ways. The information we may collect includes:

• Personal Data: Name, email address, and payment information when you register for an account.
• Usage Data: Information about how you use the application, such as feature usage and session duration, to help us improve the product.

4. AI Processing

When you use our AI features (e.g., summarization, synthesis), your data may be processed by third-party LLM providers (such as OpenAI or Anthropic) via API. We have strict data processing agreements in place to ensure your data is NOT used to train their models.
